Yuav ua li cas kom ntseeg tau qhov kev nyab xeeb ntawm cov roj ntsha lithium-ion,
Lithium ion roj teeb,

▍ Daim ntawv pov thawj PSE yog dab tsi?

PSE (Cov Khoom Siv Kev Nyab Xeeb ntawm Cov Khoom Siv Hluav Taws Xob & Khoom Siv) yog qhov yuav tsum tau ua ntawv pov thawj hauv Nyij Pooj.Nws tseem yog hu ua 'Compliance Inspection' uas nws yog qhov yuav tsum tau ua lag luam nkag mus rau cov khoom siv hluav taws xob.PSE daim ntawv pov thawj yog tsim los ntawm ob ntu: EMC thiab cov khoom lag luam kev nyab xeeb thiab nws kuj yog ib qho tseem ceeb ntawm Nyiv txoj cai lij choj kev nyab xeeb rau cov khoom siv hluav taws xob.

▍ Vim li cas MCM?

● Cov chaw tsim nyog: MCM tau nruab nrog cov chaw tsim nyog uas tuaj yeem ua raws li tag nrho cov qauv ntsuas PSE thiab ua cov kev xeem suav nrog kev yuam kom luv luv luv Circuit Court thiab lwm yam. .

● Kev pab txhawb nqa: MCM muaj ib pab neeg ua haujlwm ntawm 11 tus kws tshaj lij engineers tshwj xeeb hauv PSE cov qauv kev xeem thiab cov kev cai, thiab muaj peev xwm muab cov kev cai PSE tshiab thiab xov xwm rau cov neeg siv khoom raws li qhov tseeb, meej thiab sai.

● Muaj ntau hom kev pabcuam: MCM tuaj yeem tshaj tawm cov ntaub ntawv ua lus Askiv lossis Nyij Pooj kom tau raws li cov neeg xav tau.Txog tam sim no, MCM tau ua tiav ntau dua 5000 PSE cov haujlwm rau cov neeg siv khoom tag nrho.

Tam sim no, feem ntau ntawm kev nyab xeeb ntawm cov roj teeb lithium-ion tshwm sim vim qhov tsis ua haujlwm ntawm kev tiv thaiv Circuit Court, uas ua rau lub roj teeb thermal runaway thiab ua rau hluav taws kub thiab tawg.Yog li, txhawm rau kom paub txog kev nyab xeeb ntawm kev siv lithium roj teeb, kev tsim hluav taws xob tiv thaiv hluav taws xob yog qhov tseem ceeb, thiab txhua yam uas ua rau tsis ua haujlwm ntawm lithium roj teeb yuav tsum raug coj mus rau hauv tus account.Ntxiv nrog rau cov txheej txheem tsim khoom, kev ua tsis tiav yog qhov tshwm sim los ntawm kev hloov pauv ntawm cov xwm txheej sab nraud, xws li kev tshaj tawm, tshaj tawm thiab kub siab.Yog tias cov kev ntsuas no tau saib xyuas hauv lub sijhawm tiag tiag thiab cov kev tiv thaiv raug coj los siv thaum lawv hloov pauv, qhov tshwm sim ntawm thermal runaway tuaj yeem zam tau.Kev tsim qauv kev nyab xeeb ntawm lithium roj teeb suav nrog ntau yam: kev xaiv ntawm tes, kev tsim qauv thiab kev ua haujlwm kev nyab xeeb ntawm BMS.Muaj ntau yam cuam tshuam rau kev nyab xeeb ntawm tes uas xaiv cov khoom siv ntawm tes yog lub hauv paus.Vim muaj cov tshuaj sib txawv, kev nyab xeeb sib txawv ntawm cov khoom siv cathode sib txawv ntawm lithium roj teeb.Piv txwv li, lithium hlau phosphate yog olivine-zoo li tus, uas yog qhov ruaj khov thiab tsis yooj yim rau tawg.Lithium cobaltate thiab lithium ternary, txawm li cas los xij, yog cov txheej txheem txheej txheem uas yooj yim kom tawg.Kev xaiv cais kuj tseem ceeb heev, vim nws qhov kev ua tau zoo yog cuam tshuam ncaj qha rau kev nyab xeeb ntawm tes.Yog li ntawd nyob rau hauv kev xaiv ntawm tes, tsis yog tsuas yog nrhiav tau cov ntaub ntawv tab sis kuj cov chaw tsim tshuaj paus cov txheej txheem ntau lawm, cov ntaub ntawv thiab lawv tsis yuav tsum tau muab xam. Thaum tshav kub kub dissipation yog tsuas yog rau ib co loj zog cia los yog traction roj teeb.Vim lub zog siab ntawm cov roj teeb no, cov cua sov tsim tawm thaum them thiab tso tawm yog qhov loj heev.Yog tias cov cua sov tsis tuaj yeem ploj mus rau lub sijhawm, cov cua sov yuav sib sau ua ke thiab ua rau muaj xwm txheej.Yog li ntawd, kev xaiv thiab tsim cov ntaub ntawv kaw lus (Nws yuav tsum muaj qee yam kev siv lub zog thiab cov plua plav tsis zoo thiab cov dej tsis muaj dej), kev xaiv cov cua txias thiab lwm yam thermal rwb thaiv tsev, cua sov dissipation thiab tua hluav taws yuav tsum tau muab coj los rau hauv tus account.
